Dragonfruit Team Meeting - January 27th, 2017
Attended: Kevin, Gordon, Tyler
Updates
Transmission Test 1
Board lasted for 17 hours
Battery voltage was last recorded as 3.7V therefore unsure why board stopped transmitting
could be due to Ghost voltage or marginal short
Could also be due to Gateway crashing
After power cycling board, the board powered on and started transmitting
Transmission Test 2
Board lasted for 56.3 hours
Battery voltage was last recorded as 3.0V meaning the battery discharged before ending transmission
HOWEVER, once power cycled the board was able to send heartbeat packets
Dylan helped create a code for Arduino that would help us monitor if our XBee experienced a ghost voltage
This code will record voltages and notify when a voltage is greater than 3.3V
Having a voltage greater than 3.3V means that something other than the Voltage regulator is powering the XBee
currently we have no way of writing this data to a file
Contacted Tyrin about 3D printing the rest of housing
Testing board again with all sensors attached, and screwed into the housing
Kevin working on Gantt Chart
Gordon bringing together all necessary parts to populate another board (getting familiar with all the parts of DragonFruit)
Problems
There is currently a bizarre lack of problems
Goals
Deploy board
Program board 4 and 5
use these boards for testing
Complete redesign of new board
no parallel voltage planes surrounding charging chip if possible
new GPS and RTC components
